Huh?! Not following you here.....BPs (and most animals for that matter) have two copies of each gene, one inherited from each parent. Homozygous just means the animal has two copies of the same gene at a certain loci (location on the chromosome) they could could both be normal genes or both be abberant genes. The axanthic trait is recessive to the wild type (normal) gene, so if an animal is heterozygous for the axanthic trait it will be normal looking.Originally Posted by BaLLPAddICT
